Make one on creep.
Select it when it is done.
It should have an icon, click that or press 'n'.
Then left click where you want it make the other exit/entrance (must be on creep that you have vision of).
It should start building.
Once it is done you can transport units by right-clicking on one the two entrances, they will come out of the other one.
These two canals are connected, if one dies so does the other.
You can rally on nydus canals and the newly hatched units will go through the canal as part of rallying.
